What Travellers Say
Reviews Summary
Visitors find Pheasant Island historically significant, particularly as the site of the Treaty of the Pyrenees and for its unique alternating sovereignty. While direct access is impossible, its symbolic importance and the concept of a shifting border are intriguing. Some note the lack of accessibility as a drawback, but appreciate the historical context and the unique nature of the island.
"A historic island that is worth a visit. It is where the treaty of the Pyrenees was signed, and is owned by Spain from February-July and France from August-January. You can’t go on the island, but you can see the monument from the shore."
Alex Chadwick
"It is strange to let each country have this island for 6 months then hand it over to the other country! Why not just divide it into 2 halves and give each country a half?? Like northen half to France and southren half to Spain. Why not??"

"I am doing a school report on the island, and it sounds like a lovely place."

The Unique Condominium Status
This alternating administration is a direct result of the Treaty of the Pyrenees, signed in 1659 on this very island. This treaty was crucial in ending the protracted conflict between France and Spain. The island's neutral ground status made it an ideal location for such a significant diplomatic event, and its unique administrative arrangement has persisted for centuries, making it a living piece of European history.
While direct access to the island is highly restricted, often limited to official ceremonies or specific national park services, its symbolic importance is undeniable. Visitors can appreciate its unique status by observing it from the riverbanks of Hendaye, France, or Irún, Spain, contemplating the shared history and ongoing diplomatic dance that defines this small, yet globally significant, isle.
Historical Significance and Treaty of the Pyrenees
Beyond its role in ending a major war, the treaty also involved significant royal marriages, most notably the marriage of Maria Theresa of Spain to Louis XIV of France. This union was intended to cement peace and create a lasting alliance between the two nations. The island, therefore, witnessed not just political negotiations but also dynastic arrangements that would shape European monarchies for generations.
Today, Pheasant Island stands as a silent witness to these historical events. While visitors cannot set foot on the island, its presence in the Bidasoa River serves as a constant reminder of the complex diplomatic history between France and Spain, and the enduring legacy of the Treaty of the Pyrenees.
